Abstract
Surveys of nematode populations in tall fescue (Festuca arundinacea Schreb.) pastures in north, central, and south Alabama in 1982 and 1983 showed significant differences in frequency of occurrence of many nematode species by geographical region. Although nematode damage has been implicated in the poor adaptation of tall fescue to the sandy soils of the extreme Southeast, many plant parasitic nematode species occurred in low frequency in south Alabama pastures. There were significant differences in the frequency of occurrence of Paratrichodorus christiei (Allen) Siddiqi by region. This nematode occurred with relatively high frequency in south Alabama in both years. There were no differences in the frequency of occurrence of Helicotylenchus spp. [principally Helicotylenchus dihystera (Cobb) Sher]. However, Helicotylenchus spp. occurred with high frequency and in high numbers in all three geographical areas.
